SPECIFICATION forming part of Letters-Patent No. 721,975, dated March 3, 1903.

n Application led December 11, 1902. Serial No. 134,801. (N o model.)

Be it knownV that I, GEORGE SMITH, a citi- Zen of the United States, and 'a resident of Jersey City, in the county of Hudson andv State of New Jersey, have invented a new and Improved Clip for Detector-Bars, of which the following is a full, clear, and exact description.

This invention relates to a means for supporting detector-bars; andthe object sought is to provide a clip lying closely and compactly alongside the rail and adjustable-to rails of various sizes and to meet other conditions liable to arise in railway construction.

This specication is an exact description of one example of the invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is an inner side elevation of the clip. Fig. 2 is a cross-section on the line 22 of Fig. 6. Fig. 3 is anouter side elevation of themotion-plate. Fig. 4 is an inner side elevation of the same. Fig. 5 is a section on the line 5 5 of Fig. 4. Fig. 6 isan outer side elevation of the clip and motion-plate, showing the detector-bar lowered; and Fig. 7 is a similar View showing the detector-bar raised.

The body of the clip is formed with a horizontal groove a for the reception of the outer base-fiange of the rail and with a transverse orifice 0b receiving the outer end of the hookbolt b, the nut whereof bears against the outer face of the body, the hook-bolt being passed under the rail and engaged with theinner fiange thereof. YInits upper portion the body of the clip is formed with a vertically-elongated oriflce a2 running transversely through it and communicating at its inner side with a groove a3, formed in the inner face of Vthe clip-body and running upward from slightly below the orifice a2 to the upper extremity of the body. In this groove a3 is set loosely the carrier c. Said carrier is held rigidly in place and yet capable of vertical adjustment-by means of a bolt d, which has at its inner end an enlargement d', with an annular flange d2, said parts cl and d2 forming a flanged stud and the enlargement d bearing against the carrier cto hold it. d3 represents the nut on the bolt cl, and d4 represents an antifrictioncollar set on the enlargement d' and lined with a suitable gasket, yas illustrated. At its upper portion the carrier c is provided with an inwardly-projecting lug c', which lies just above the aforesaid flanged stud d' d2.

c indicates the motion-plate,which is formed on its inner side at each end with an inwardlyprojecting lug el'. These lugs aread'apted to `bear under the detector-bar fand assist in holding the detector'- bar and motion -plate connected. Complete connection is effected by bolts passed-"through the parts e and f, for which purpose the motion-plate is provided with orifces e2, as shown. On its outer side the motion-plate is formed with a lcam c3, the middle of which is dipped downward, as best shown in Fig. 3. The flange d2 lies against the front face of the motion-plate, and the said cam e3 bears its lower face on the collar d4, as indicated in Fig. 2. Now it is clear that by 'this arrangement any longitudinal motion of the detector-.bar must be accompanied by a vertical movement and Athat'ths vertical movement is brought about by thevcam e3 riding on the flanged stud of the carrier. The lug c' prevents the detector- 'bar from jumping out of place owing to the engagement between the said lug andthe top faceof the cam e3. The detector-bar is connected with the switch mechanism in the usual manner.

It is clear that by this construction the clip may be placed snugly alongside of-theirail and its working parts be held above the baseylian ge. Y employed moving parts of the clip were placed In certain constructions heretofore below the base-flange or adjacent thereto, and they are thus yliable to become clogged with icepand ballast from the road-bed, so as to -prevent the proper working of the detectorbar. This will be entirely obviated by the construction forming the subject-mattei' of my invention. Further, it will be observed that the carrier c maybe very readily adj usted so as to place the detector-bar at any desired position with respect to the ball of the rail. The bolt h may be withdrawn at will, so that the clip may instantly be fastened to a rail of any sort. This avoids providing separate clips for different sizes of rails.

Various changes in the form, proportions,

IOO

and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of a body, means for fastening the same in place, said body having a portion projected upward from the plane of the base-ange of the rail, a carrier adjustably mounted on the upper portion of the body and having a lug projecting inward, a stud projecting from the carrier below the lug, and a motion-plate having a cam bearing between the stud and lug.

2. The combination of a body, means for holding it in place, a carrier-plate mounted on the body, a motion-plate having a cam thereon, and means projecting from the carrier and engaging the can). of the motionplate, said means comprising a flanged stud and a lug above the same.

3. The combination of a body, means for holding it in place, said body having an upwardly-projected portion with a verticallydisposed orifice, a carrier-plate,l a bolt having au enlargement engaged with the carrierplate, said bolt being fastened in the orice of the body, a lug projected inward from the carrier above the enlarged portion of the boit, a motion-plate, and a cam thereon, said cam bearing between the bolt and lug.

4. The combination of a body, means for holding it in place, a carrier, a bolt adjustably mounting the carrier on the body, a lug projected from the carrier, a motion-plate, and a cam carried thereon, said cam bearing between the bolt and lug.

5. The combination of a body, means for holdin git in place,a carrier-.adj ustably mounted thereon, two members projected from the carrier, a motion-plate, and a cam mounted on the motion-plate and bearing between the said two members of the carrier.

6. The combination of a body, means for holding it in place,a carrier adj ustably mounted en the body, a motion-plate having a cam thereon, and means projecting from the carrier and engaged with said cam, for the purpose specified.

7. The combination with a rail, of a body portion, means for fastening the same to the base-flange thereof, the body portion projecting upward from said means, a stud carried by the body portion above said means and projected inward toward the rail, a lug carried by the body above the stud and also projecting inward toward the rail, and a motionplate having a cam thereon, the cam bearing between the said stud and the lug.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE SMITH.
